NHL PA150 Supersonic Plasma Atomization Pulverization System

NHL PA150 supersonic plasma atomization powder making system adopts the plasma wire atomization powder making technology independently developed by Navector Laboratory. The technical principle is that the raw metal wire is produced by one or more plasma torches. The high-temperature and high-speed thermal plasma jet is simultaneously melted and atomized and broken into fine metal droplets, which are finally solidified and cooled into fine metal powder.

The new generation of plasma wire atomization powder making equipment independently designed and manufactured by Navector Laboratory New Additive Manufacturing Research Institute has broken the technical blockade of the United States and Canada. The equipment has both low cost, low doping and production capacity. With many advantages such as expansion, stable mass production of active metals such as titanium and vanadium and refractory metal powders such as tungsten and molybdenum can be realized.
